If you have one of those 5050/WS2811 aka WS2812 strips and you want to "wear" it, I have a board for you.
Here are the specs:
5V power supply
0.05" programming header
UART input (allows pixel or sequence control)
11mm wide (0.45")
25mm long (1")
32mm long (1.25") - version with memory
optional SOIC SRAM or EEPROM
There are 4 boards on the panel, 2 with memory option.
